FIELD OF INVENTION
The Invention relates to a pressure-sensitive adhesive composition, the suitable for application to human or animal skin is a method for preparing such adhesives and the use of of such adhesive for the preparation of a wound dressing or an adhesive wafer for a An ostomy appliance or the use of the adhesive for fixing of Stomaverbänden and their all-round seal for securing wound dressings, for Fixing of urine collecting devices, wound drainage associations, orthoses and prostheses and for protection of skin areas and parts of the body against pressure, impact and friction; The invention also relates to wound dressings or ostomy appliances such adhesive composition.
BACKGROUND THE INVENTION
For the above mentioned Applications are currently used various skin adhesive.
A very widespread embodiment of skin adhesives has a self-adhesive elastomeric matrix, in the water-swellable particles, so-called hydrocolloids, are dispersed.
Adhesive compositions, comprising hydrocolloids, active for many years are known. Thus, the patent discloses <patcit><text>US 3 339 549</text></patcit> a blend of a rubbery elastomer, such as polyisobutylene, and one or more water-soluble swellable or hydrocolloids such as a powdery mixture of pectin, gelatine and carboxymethylcellulose. The adhesive composition carries a water Film on a surface thereof. A composition of this type is under from ER Squibb & Sons Inc. the trademark "Stomahesive" commercially available and is used as a skin barrier around stomas to skin damage by the exiting from the stoma aggressive fluids to prevent; the composition is also used for adhesive wafer for ostomy appliances.
at Adhesive compositions of this type, the polyisobutylene is for achieving the adhesive properties responsible, while the dispersed hydrocolloid powders liquid absorb and enable the adhesive to the fact that it also on wet Skin liable (wet adhesiveness, "wet tack"). These compositions also enjoying increasing acceptance as wound dressings for dermal ulcers, burns and other weeping Wounds.
On The main problem with which one, with conventional adhesive compositions comprising hydrocolloids, faces, is their susceptibility for a Breaching when body fluids are exposed. When the compositions are used as skin barriers are, for example, around stomas, although the liquid absorption he wishes, but results excessive swelling means that the composition loses its cohesion, which to open leaks and leads, that the barrier be replaced more often must be than desirable from the viewpoint of skin protection ago , where very often a residue remains on the skin, difficult to remove, in many cases is.
At the Bandaging wounds resulting the contact with the wound exudate in a similar manner to a disintegration the adhesive, which means that when changing the dressing residue in the remain wound affect the healing process can. When using leakage can also occur, which is a part shortened Period of use means and partly the risk of contamination of the can increase wound with bacteria and other microorganisms.
adhesive are further also for attaching devices such Harnableitungsvorrichtungen to Collecting urine from incontinent persons employed. disintegration of the adhesive agent due to contact with urine turn means a risk of leakage and a reduction in service life.
adhesive are further also for securing orthoses and prostheses (for Example of breast prostheses) and for protecting skin areas or body parts against pressure, impact and Friction used. In these cases is primarily sweat secretion, which can cause swelling and disintegration of the adhesive. When removing the adhesive residues remain on the skin, turn those mentioned above brings disadvantages.
<?page 3?>
to Improving cohesion of adhesive compositions were already taken a number of attempts.
So , as a method for improving the integrity of the adhesive the use of hydrocolloids described, which in turn cross-linked are (for example cross-linked carboxymethylcellulose (CMC), cross-linked Dextran or other water, but insoluble hydrocolloids). solve these materials due to the crosslinked structure is not on. During the Swelling take the individual particles accordingly a gelatinous Structure on, however, no coherent gel formed, since the macromolecules the crosslinked hydrocolloids are set in the gel network, the is formed by the individual particles. Since no coherent gel present, the cross-linked hydrocolloids are dissolved and in suspended the body fluids, so that the effect according to the integrity of the swelled adhesive is limited.
alternative to the attempt was made to the cohesion of the swollen Adhesive by increasing Cohesion the elastomer phase to increase (As described in some of these prior art patents is). The elastomer phase is accordingly during the swelling process not easily blasted by the expanding hydrocolloids. However, this method has a number of disadvantages: <ul><li>- The Water absorption rate, and thus the wet adhesiveness of Adhesive ( "wet tack ") is reduced.</li><li>- By reinforcement Cohesion receives the elastomeric matrix stronger elastic properties. When the hydrocolloids absorb water and swell, thereby is an enlargement of the dimensions of the adhesive promoted. Due to the elastic properties of the matrix is no relaxation of occurring in the adhesive stresses by plastic deformation possible. Instead, occur around the swollen area around folds in the adhesive. In these pleats the adhesive agent loses the contact with the body fluids exposed skin, resulting in the risk of leakage.</li></ul>
The patents <patcit><text>US 4192785</text></patcit> and <patcit><text>US 4551490</text></patcit> describe introducing a cohesion reinforcing Agent into the adhesive composition, for example the introduction a natural or synthetic fiber material, of finely divided cellulose, cross-linked dextran, cross-linked carboxymethylcellulose or a Starch-acrylonitrile graft copolymer. From the cohesion reinforcing Agent is determined that it is the rate of hydration of the composition controlled, whereby the resistance against the break of body fluids elevated is.
The patent <patcit><text>US 4477325</text></patcit> describes introducing a mixture of an ethylene-vinyl acetate (EVA) copolymer resin in the adhesive composition. After mixing and molding the composition of ionizing radiation is subjected to to produce a crosslinked polymer network which consists of EVA or EVA and another cross-linked resin. The crosslinked matrix is a controlled swelling result.
The patent <patcit><text>US 4496357</text></patcit> describes Dumping of fumed silica in adhesive compositions to control the swelling.
<patcit><text>EP 122 344 B1 0</text></patcit> describes the introduction of one or more natural or synthetic polymers, which enables are to develop elastomeric properties when hydrated, in the adhesive composition, for example from gluten and long chain Methyl vinyl ether / maleic acid polymers. It is stated that the adhesive composition to erosion by moisture and body fluids is resistant.
The patent <patcit><text>EP 0340945 B1</text></patcit> describes incorporation of some polycationic hydrocolloid particles in a hydrocolloid composition. It is stated that the mixture of polycationic, polyanionic and neutral hydrocolloids increased Togetherness results without at the same time reduces the absorption capacity is.
WHERE 95/18191 A1 discloses a water-dispersible adhesive composition, which is a branched copolyester containing a sulfomonomer having low molecular weight contains.
<patcit><text>US 5512612</text></patcit> is a pressure sensitive adhesive to which a water-dispersible containing polymer, For example, a polymer comprising poly (alkoxyalkyl) acrylate units contains.
<patcit><text>EP 0781538 A</text></patcit> (in front the priority date filed the present application, however, after ver<?page 4?>published) discloses a hot melt adhesive composition, the at least one water-dispersible copolyester, a containing plasticizer and a tackifier compatible therewith.
On Another major problem with conventional Adhesive compositions comprising hydrocolloids is their limited ability to moist body surfaces stick. Therefore, there is a particular need for an improved Adhesive composition having improved adhesion to moist skin in the care of stoma patients, since it is often difficult, the skin while around stomas to keep the replacement of an ostomy appliance completely dry.
at the existing adhesives is the adhesive surface the self-adhesive elastomeric matrix while the hydrocolloids below the surface are embedded in the elastomer matrix. It is therefore necessary for the absorption of moisture penetrating the water through the elastomeric matrix through, before reaching the water absorbing hydrocolloids. This delays the Water absorption and has the result that the adhesive not immediately on moist surfaces liable (wet adhesiveness).
Skin problems, arising in connection with an ostomy, differ skin problems, generally with adhesives for skin (dressings or Patches) occur because the adhesive of ostomy appliances during long periods be applied permanently to the same location (chronic irritation) while other adhesives for the skin usually only for a short time on the same Location can be applied.
The European Patent application <patcit><text>EP 0 017 401 A1</text></patcit> discloses articles having adhesive properties, the For example, for Protective plaster or NGOs or as rings, discs or the like for surgical applications such as for Ostomy appliances are suitable and which have a plastic matrix containing a product, the heating of the common of one or more polyhydric alcohols and gelatine and / or a course occurring high molecular weight polysaccharide gum and / or resin, which is a copolymer of a vinyl ether and an organic acid anhydride and / or represents the corresponding free acid thereof, results. A polyvinylpyrrolidone may be added as an adhesive modifier will.
The published European Patent application <patcit><text>EP 0343807 A2</text></patcit> discloses an adhesive dressing with absorbent capacity and controlled hydration of about 30 - 65% of polyisobutylene, 10 - 30% polyvinylpyrrolidone, 2-20 % Modified starch, 2-20 % Pectin, 0.1 to 10 % Acrylic polymer and a 0 - 1 % Fibers.
The European Patent publication <patcit><text>EP 0063898</text></patcit> disclosed a microporous Tape comprising a porous backing layer and a microporous having adhesive layer, a rubbery elastomer such as polyisobutylene one or more water-swellable hydrocolloids and optionally also other substances. On Copolymer of polyvinyl pyrrolidone and vinyl acetate can be used as means be used for tackifying.
Therefore there is still a need for an adhesive composition which very rapid water absorption and water retention is to the wet adhesiveness to improve, and at the same time against disintegration on contact with body fluids resistant is.
It it has now been surprisingly found a way that an adhesive composition comprising a water contains dispersible polyester, very rapid water absorption and improved wet adhesiveness shows and at the same time to disintegration upon contact with body fluids resistant is.

The Invention further relates to a process for preparing a pressure-sensitive Adhesive composition for application to human or animal skin and is suitable dispersible the one in water containing polyester, as well as the use of such adhesive for the preparation of a Wound dressing or an adhesive wafer for an ostomy appliance or the use of the adhesive agent for securing of and Stomaverbänden their all-round seal for securing wound dressings, for Fixing of urine collecting devices, wound drainage associations, orthoses and prostheses and for protection of skin areas and parts of the body against pressure, impact and friction, and for the preparation of <?page 5?>Wound dressings or ostomy appliances, which such an adhesive composition.
DETAILED DESCRIPTION OF THE INVENTION
The This invention relates to a pressure-sensitive adhesive composition, the suitable for application to human or animal skin and contains: <ul><li>a) a water-dispersible polyester,</li><li>b) one or more polymers selected from polyolefins or copolymers selected or polymer blends thereof are, and / or one or more physically cross-linked elastomers, under the block copolymers of styrene and one or more Olefins consist selected are, and / or one or more polyethylene glycols and / or glycerol,</li><li>c) optionally a butene polymer or butene copolymer,</li><li>d) optionally, a tackifying resin, the hydrogenated partially or completely can be,</li><li>e) optionally a microcrystalline wax,</li><li>f) optionally a plasticizer,</li><li>g) one or more hydrocolloids and</li><li>h) optionally a pigment.</li></ul>
By introducing a water-dispersible polyester in a adhesive elastomeric matrix an improved adhesion in scored a humid environment. This is due to the fact that the water-dispersible polyester to the surface of Adhesive is present and is capable causing an immediate absorption of water. The water Polymer further remains tacky even after the absorption of water, which in contrast to non-absorbing elastomers is that at usual skin-friendly adhesives are used, which is why a better liability long periods is achieved.
The pressure-sensitive adhesive composition of the invention typically contains a water-dispersible polyester in a proportion 10-50 %, One or more polymers selected from polyolefins or copolymers or polymer blends are selected therefrom, and / or one or more physically cross-linked elastomers, the among block copolymers of styrene and one or more olefins consist selected are, and / or one or more polyether glycols and / or glycerol in a proportion of 10-70%, a butene polymer or butene copolymer in an amount ranging from 0 to 15%, a tackifying Resin which completely or partially can be hydrogenated in an amount of 0 to 30%, a micro-crystalline resin in an amount ranging from 0 to 10%, a Plasticizers in an amount ranging from 0 to 10%, one or more hydrocolloids in an amount of up to 50% and a Pigment in an amount ranging from 0 to 5%.
Of the water-dispersible polyester is preferably a water-dispersible branched polyester.
The Use of a branched water-dispersible polyester in adhesives results in the following benefits: <ul><li>- The adhesive shows improved adhesion in moist environments by being absorbed of water and gives a better wet adhesiveness compared with conventional Adhesives based on non-absorbing self-adhesive Elastomers. The branched water-dispersible polyester contributes further contributes, in which he gives a good adhesion for extended periods since the stickiness the elastomer maintained even after the absorption of body fluids remains.</li><li>- The Adhesive leaves due to the water-dispersibility of the polyester by washing easily removed with tap water, wherein the adhesive but by body fluids is not impaired. The body fluids ionic solutions, in which the polyester component is not dispersible. On the Skin remaining Adhesive residues can be so easily removed with tap water.</li></ul>
Suitable water-dispersible branched polyester are polyesters with following physical properties: a Brookfield Thermosel viscosity at 177 ° C 1000-500000 mPa · s, preferably 1000-50 000 mPa.s and preferably 2000-8 000 mPa · s, a ermit in ball-ring test<?page 6?>telter softening point 50-150 ° C, and more more preferably 80-90 ° C, after ASTM D 5 detected in the penetration test hardness 5-50 dmm, preferably about 30 dmm according to ASTM D 3418 and a specific glass transition temperature T<sub>G</sub> 5 to -10 ° C, preferably about -5 ° C.
A Reducing the amount of hydrocolloids is possible as the branched in Water dispersible polyester contributes to the absorption. A Reducing the amount of hydrocolloids improves the stability of the adhesive due to the reduction of the disintegration, the considerable by the Swelling of the hydrocolloids in conventional skin friendly adhesives after absorption of body fluids is caused.
Suitable Hydrocolloids are naturally occurring hydrocolloids such as guar gum, locust bean gum (LBG), pectin, alginates, gelatine, xanthan or karaya, semisynthetic Hydrocolloids such as cellulose derivatives (e.g. salts of carboxymethylcellulose, Methylcellulose and hydroxypropylmethylcellulose), sodium starch glycolate and synthetic hydrocolloids such as polyvinyl alcohol, polyethylene glycol or polyacrylates.
pigments can as fillers or dyeing the adhesive of the invention may be used. Suitable pigments are Pigments as conventionally be used in adhesive compositions, for example, titanium dioxide or zinc oxide. Zinc oxide offers the advantage that it is an anti-bacterial Effect shows.
